The invention provides a virtual data center visual management method based on a Cairngorm framework, and belongs to the technical field of computer application. The virtual data center visual management method based on a Cairngorm framework uses the Cairngorm framework, uses the flex technique as the foreground development language, takes ActionScript as the logic processing language, is applied to the experimental scene of resource management or software definition network of a virtual data center, can provide a visual Web front end, is integrated with various SDN mainstream controllers and displays the global network topology of the virtual data center. Through the Web front end, the virtual data center visual management method based on a Cairngorm framework can control the life cycle of each component in the network topology, and can complete works, such as issuing of an OpenFlow flow table, accessing of a component console, and accessing of the UI interface of different SDN controllers.
